Where this comes from

Abstract

RNA polymerases (RNAPs) control the first step of gene expression in all forms of life by transferring genetic information from DNA to RNA, a process known as transcription. In this issue of Cell, Webster et al. and Wu et al. report three-dimensional structures of RNAP complexes from chloroplasts.
